Subject: m4: Stick to C17 standard
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=94ec72b332dce71a2756560ddf738f864e3c853d;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

m4: Stick to C17 standard

GCC15 imposes C23 by default and 1.4.19 release has gnulib version which
can not be compiled without errors, while new release of m4 is in progress
we might use C17 until then and use GCC15 to compile it

For scarthgap also add it in BUILD_CFLAGS.
